If you’ve read this far, we might as well cut to the chase.

We love and respect our competitors, because without them we can’t be different.

If you think your master is going to sound better by sending it to a “famous” person in NYC / Maine / Los Angeles, then, we aren’t the mastering house for you. We don’t want to be famous, we want YOU  to be famous. What we do matters, but not at the expense of our integrity. We are not followers, we are independent thinkers, honest and logical, and immune to the hype/bs that is most of the entertainment industry. If this sounds like something you’re interested in, please call us, as we would love to make your record sound better than you ever thought it could.
